F. KOSTLAN I AIR TUBE POST Filed Sept. 20', 1921 FRANK Kosrnaiw -AIRJ-TUBE PEST.

Application filed. September To (17. who m, iii 12mg concern:

it known that-L'FRANK Kos'rLAN, a

citizen of the United States, residing ,at Eraer, in the county of; Tania andState of Iowa, have invented certain new and useful In'iprovements in Air-Tube Posts; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for serving compressed air for the inflation of pneumatic tires, and the object of the invention is to produce a device to carry the air-tube which will afford a wide range of movement for the tube; will support it' in a nearly vertical position when not in use, and when in use will be practically balanced, so that the operator does not need to hold to the tube to prevent its pulling away.

The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawin in which:

Fig. l is a side view of the device as in use. Fig. 2 is a side elevation, partly in section, showing; in larger detail the main features or the invention.

In the drawing the numeral 5 denotes an air-pipe located near a street curb 6, and

leading to a source of compressed air, not shown. The pipe is provided with a suitable valve 7 to control the flow of air. Adjacent to this pipe is mounted a standard 8, which in practice is made of section oi." large gaspipe, a reducing coupling; 8 and "n upward extension 8" of small pipe. ound the cou ling isfitted bracket 9, with an outer eye to enclose the air-pipe, and to this bracket is attached a hook 10. (3n. the extension 8 is swiveled an angled supporting arm 11, formed or a section of pipe 11- to Fit revolubly on the extension, an elbow ii", and a diagonal extension 11 Near the end of the extension is pivoted a stirrup 12 having a hub 12 to receive the main tube-carrying arm 13. and provided with a set-screw 12 for securing the arm adjustably in position. This arm is bent at 13, and to the shorter limb is attached by a set-screw 14. a slidable weight ii by which means the arm and its depending tube may be nicely balanced when in the operative position shown in Fig. l. The outer end or" the arm is formedas a goose-nech i3}, and from this hangs pivot adapted tocarry the ,i i i prevent a short 1 the t connects pipe, {tilf the. other coupling 16. end of the airpipe the tube is passed through an eye in the pivot-pin 17 support ing the stirrup 12. i

The operation of the d vice is clearly indicated in F l, where an automobile indicated in dotted ontline, in position io tire inflation. It will be evident that t operator, holding the tube, may move to wheel, and inflate its tire. The weight ing properly adjusted, the arm 13 may be exactly balanced, when in the position shown in Fig. 1. it is then held depressed merely by the preponderating weight of the free end of the tube, and t-l'lGf'ti no retracting" pull on the tube. He thus full use of both hands, which is a matter of great convenience in the manipulation of nipple caps and in the testing (it pressure with pressuregage. it is to be noted that the depression of the arm is limited by the end of the diagonal ar 11, so that no part of it comes in contact with the car or its top. VJhen the inflating operation is completed, the operator sin ply lifts the tube, when the weight, with an accelenting leverage, lifts the parts to the positio shown in dotted outline, the tube being: hang behind the hook so as to be completely out or" the way, and not swing in the wind.

Having thus described my invention, claim:

An air-tube support, comprising a standard, a member swiveled tube-supporting arm pivoted to so her, and having an oppo wardly inclined arm with ing weight attached thereto tube-supporting arm is pr when depressed, but when erect.

2. An air-tube standard, an upwioi; swiveled thereon, inn arm hinged at, cent the ap angle to a point near the outer end oi said member to swing in a rertia'al plane, and balancing weight attached to said I counterbalance he time and its part of the arm.

3. An air support, comprising a 'sing a counterbalancing Weight carried by said arm.

4. An air-tube support, comprising a. standard, a member swiveled thereon, a vertically swinging arm hinged thereto by a tube-carrying pin, a depending, tube-'carrying shoe at the outer end of the arm, and

a counterbalancing Weight attached to the arm on the other side of the hinge.

5. An air tube support, comprising a standard, a member having a diagonal 'extension, swiveled thereto, a stirrup hinged to said extension, and a tube-supporting arm attached to said stirrup, the end of the extension vforming a stop to limit the'depression of said arm. c

In testimony whereof I afiix my signature in presence of two Witnesses. r
